I am having a problem seaching my Plan object with Plan.find() using  
an array object that appears to be setting itself up incorrectly.  
Here is what I am seeing.

NoMethodError in Generate reportsController#advanced\_plan\_summary

undefined method `each’ for #Plan:0xb7605a24

/usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/  
active\_record/base.rb:1860:in `method_missing' app/controllers/generate_reports_controller.rb:419:in`advanced\_plan\_summary’

Request

Parameters: {“plans”=\>“3/29”}

How is Ruby setting up my arrays as a string like this instead. Has  
anyone seen this before?

I am using  
Rails 1.2.3  
Ruby 1.8.6  
gems 0.94

Hi!  
I think that if what you get is x, you are calling x.each() but x is an  
object not an array.

I found the problem. You were correct. I kept thinking Ruby was  
misformating the parameter straing. Thinking I should see and array  
in Parameters: {“plans”=\>“3/29”}. This was correct.

@plans = Plan.find(params[:plans])  
My problem was with this code

for plan in @plans  
…  
end

I had to change it to  
for plan in @plans.to\_a  
…  
end

and it worked. Thanks
